Building Trades don't work for love

The building trade industry is flawed. Why is it so many builders get away with not paying Trades for their hard-earned labour? Businesses going into liquidation/bankruptcy and starting under another business name? No other business can get away with this kind of operation. One simply does not walk into a business take items/services and state "sue me" or "Ill pay when I feel like it"!

Small building trade businessess are ruined and families are struggling due to this insanity and the ability for builders to simply say "can't/won't pay"? Resulting in thousands of dollars in loss. This is not OK !

Electricians, Plumbers, Carpenters, Brickies, the list goes on, it's an injustice, insulting & clearly WRONG, in this day and age for this to be occurring so often.
